webrtc client cannot view on some networks

[tonyportersec]

Config:

RTSP CAM -> WCS ->WebRTC ->ios safari,

On some network the same ios device can view the webrtc video, but some not.
USE LTE cannot view, use some wifi can, some cannot.

If i use the failed network to test on the demo page's Player, it show Failed by ICE timeout.

What setting do i need to do on the WCS? Thanks

Good day.

Seems like either network is too bad or some media ports from range you use on server (31001-32000 UDP and TCP by default) are blocked
In the first case, increasing ice_keep_alive_timeout may help:

ice_keep_alive_timeout=30

But, in the second case, only the ports unlocking by network provider will help. You can also change media ports range, for example

media_port_from        =10001
media_port_to          =20000

but this range may also be locked.
You can also use HLS to play the stream in iOS Safari, it requires only one port (8082 for HTTP and 8445 for HTTPS by default), and this port can be easily changed if locked.

I knew the reason, the ip on the flashphoner.properties is set to the local network IP.

Yes, if the server is behind NAT, ip should be set to external IP address, this is mentioned in docs.
